Cecilia’s research focus is on climate and climate change in the high latitudes on Earth, especially involving the cryosphere. She uses a variety of models for her research, from simple reduced models to sophisticated earth-system models. She has worked with several Astrobiology students to teach them about climate modeling and conduct simulations relevant for Earth’s deep past and exoplanet climates.
